Comparative studies on polycyclic aromatic hydrocarbon (PAH) pollution in residential air of Hangzhou (China) and Shizuoka (Japan) were conducted in summer (August,2006) and winter (January,2007).Total concentrations of 8 PAHs ranged from 7.1 to 320ng/m3 and 0.15 to 35 ng/m3 in residential air of Hangzhou and Shizuoka,respectively.Air PAH concentrations in smoking houses were higher than that in nonsmoking houses.In nonsmoking houses,mothball emission and cooking practice were the emission sources of 2- and 3-ring PAHs in Hangzhou,respectively.The 2- and 3-ring PAHs were from use of insect repellent,kerosene heating and outdoor environment in nonsmoking houses in Shizuoka.The 5- and 6-ring PAHs in residential air were mainly from outdoor environment in both cities.Toxicity potencies of PAHs in residential air of Hangzhou were much higher than that in Shizuoka.
